[0024] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0025] Reference Figures 1 to 5 As shown, a switch cabinet bus plug-in device 100 with a shielding function provided by an embodiment of the utility model includes: a plug-in terminal 101, a plug-in socket 102, a shielding cover plate 103, etc.

[0026] The plug-in terminal 101 is used to achieve plug-in; the plug-in terminal 101 can be of various types, which can be selected according to actual needs.

[0027] The socket 102 is used to accommodate and fix the plug terminal 101. Of course, the socket 102 can also accommodate a circuit board, and the position of the plug terminal 101 relative to the socket 102 can be configured according to actual needs. Due to insulation requirements, the socket 102 is often made of plastic material.

[0028] The shielding cover 103 is fixedly mounted on the socket 102 at a position where shielding is required; as a preferred solution, the socket 102 is provided with an embedding groove 1021, and the shielding cover 103 is embedded in the embedding groove 1021. The embedding groove 1021 is a rectangular groove; the shielding cover 103 has a rectangular outer contour. The end face of the shielding cover 103 is aligned with the end face of the socket 102.

[0029] Optionally, in some embodiments, the embedding groove 1021 is a rectangular groove; and the shielding cover plate 103 has a rectangular outer contour.

[0030] Optionally, in some embodiments, an end surface of the shielding cover plate 103 is aligned with an end surface of the socket 102 .

[0031] By adopting such a solution, the position of the shielding cover 103 can be effectively limited.

[0032] The shielding cover 103 includes a plurality of splicing units 1031 , and a splicing structure 1034 is provided at the edge of the splicing unit 1031 so that the splicing unit 1031 can be spliced ​​with another splicing unit 1031 into a whole; the shielding cover 103 is formed by repeatedly splicing the splicing units 1031 .

[0033] By adopting the above scheme, an embedding groove 1021 that is an integer multiple of a standard size can be designed as needed. This standard size is also the unit size of the splicing unit 1031 of the shielding cover 103. In this way, no matter what the size of the socket 102 itself is, as long as the corresponding embedding groove 1021 is set at the position that needs to be shielded, and then sufficient splicing units 1031 are configured in integer multiples, the area can be shielded and protected.

[0034] Reference Figures 2 to 5 As shown, optionally, in some embodiments, the splicing unit 1031 only includes: a covering portion 1032. The covering portion 1032 is at least constructed to have a flat plate structure. The splicing structure 1034 is constructed as a groove and a protrusion at the edge of the flat plate structure. This type of splicing unit 1031 is only used to form the middle part of the shielding cover plate 103. Optionally, in some embodiments, the groove and the protrusion are both extended to the plate surface direction of the flat plate structure.

[0035] Reference Figure 3 As shown, optionally, in some embodiments, a part of the splicing unit 1031 also includes: a covering portion 1032 and a positioning buckle 1033. The positioning buckle 1033 is formed on at least one side of the covering portion 1032; the socket 102 is provided with a positioning slot 1022 for inserting the positioning buckle 1033. This type is used to combine the shielding cover 103 with the socket 102 after the splicing is completed. Optionally, in some embodiments, the end of the positioning buckle 1033 is provided with a avoiding notch 1035. This makes it smoother when snapping.

[0036] As a preferred solution, the outline of the splicing structure 1034 includes at least an arc, which can provide multiple horizontal dimensions of positioning. At the same time, the edge of the flat joint structure is not straight up and down, but has a certain slope, or adopts a certain interference fit, so as to more firmly stabilize the connection formed by the splicing.

[0037] Optionally, in some embodiments, the covering portion 1032 is at least partially made of metal material, and the positioning buckle 1033 is made of plastic material.

[0038] Optionally, in some embodiments, the covering portion 1032 includes: a shielding layer 1032a and a bonding layer 1032b. The shielding layer 1032a is made of a metal material; the bonding layer 1032b is made of a plastic material; wherein the bonding layer 1032b and the positioning buckle 1033 are integrally formed.

[0039] The shielding layer 1032a and the bonding layer 1032b may be integrated into a whole by using a gluing process or a pressing process.
